Description

Technical Field

[0001] This utility model relates to the field of furniture technology, and more specifically, to drawer lamps and cabinets for expanding the illumination angle. Background Technology

[0002] Cabinet lighting technology has undergone years of development, demonstrating unique advantages in light sources, intelligent control, and installation design. Significant innovations in light source technology have led to LED light sources dominating the cabinet lighting field due to their energy efficiency, environmental friendliness, long lifespan, small size, high luminous efficiency, and excellent color rendering. For example, MiniLED backlighting technology has drastically reduced the thickness of lamps, enhancing aesthetics and increasing penetration in high-end products. Intelligent control technology is becoming a new trend, with voice control and human body sensing functions making cabinet lighting more convenient. Human body sensing technology allows lights to automatically turn on when cabinet doors or drawers are opened and automatically turn off when closed, offering both convenience and energy savings. Installation design technology increasingly emphasizes convenience and aesthetics. Examples include recessed cabinet lights and external light fixtures. Recessed cabinet lights, through special design, can be directly installed into the recessed cabinet without secondary processing, saving internal cabinet space and improving space utilization efficiency and overall aesthetics.

[0003] Chinese Patent Application Document 1 (Application No.: 2023224759545, Application Date: 2023.09.12) discloses an L-shaped luminous cabinet light, including an aluminum base shell 1', and LED beads 2', reflective paper 3', and diffuser plate 4' disposed inside the aluminum base shell 1'. The reflective paper 3' is located directly behind the LED beads 2', and the diffuser plate 4' is located directly in front of the LED beads 2'. An L-shaped lampshade 4' is installed on the front of the aluminum base shell 1', and the L-shaped lampshade 4' is located directly in front of the diffuser plate 4'. The dimming and color-changing functions of the above solution cannot meet the lighting requirements while also protecting the user's eyes. At the same time, the L-shaped luminous cabinet light has many parts, is large in size, occupies a lot of cabinet space, and affects the aesthetics. The light reflection of the prism surface 6' is relatively disordered, and the prism effect only has a partial light enhancement effect, which has limited practical effect on increasing the light scattering area of ​​the product.

[0004] Chinese Patent Application Document 2 (Application No.: 2021218843375, Application Date: 2021.08.12) discloses an LED side-emitting cabinet light strip, including a strip-shaped base and a plug. A partition is provided on the strip-shaped base, and a connecting plate is provided at the upper end of the partition. Two symmetrical first slots and an inclined second baffle are provided in the front area of ​​the strip-shaped base, and a front light panel with LED beads is inserted between the two first slots. The upper end of the second baffle is connected to the lower surface of the connecting plate through an L-shaped bracket, and the L-shaped bracket and the bottom surface of the second baffle cooperate to form a second slot. A third slot is also provided in the front area of ​​the strip-shaped base, and a front lamp cover is inserted between the second slot and the third slot. A hand gesture sensing drive board is provided at one end of the strip-shaped base, and an infrared sensor is electrically connected to the hand gesture sensing drive board. A side light panel is inserted in the rear area of ​​the strip-shaped base, and a side lamp cover is provided outside the side light panel. A touch drive board connected to the side light panel is provided at the other end of the strip-shaped base. The above solution also suffers from the problem that the strip base is too thick, taking up a lot of cabinet space and affecting the aesthetics. Furthermore, the light scattering range of this solution is narrower than that of the aforementioned Chinese patent application document 1; at the same time, it does not have the function of protecting the user's eyes from light scattering.

[0005] Chinese Patent Application Document 3 (Application No.: 2024204844126, Application Date: 2024.03.13) discloses a cabinet-mounted lighting fixture, including a profile and a lampshade. The profile is connected to a connecting component. The profile includes a left panel, a middle panel, and a right panel. The profile has a switch opening. The left panel has a left hook and a left support, and the right panel has a right hook and a right support. The profile includes an upper space. The lampshade includes a vertical panel and a horizontal panel. The left inclined panel and the vertical panel enclose the left space, and the left hook engages with the left... The space is formed by a horizontal plate, a right-angled plate, and a right-angled connecting plate. The right hook engages with the right space, and the lighting device engages with the lampshade. The sensor switch, lighting device, and power supply are all connected to the lamp wire terminals. The connecting components include connectors and positioning components. The connectors include an outer zone and an inner zone. The outer zone is connected to the cabinet via the positioning component. The inner zone and part of the outer zone are inserted into the upper space. The outer zone has an outer zone slot. The positioning component includes a positioning plate and expansion screws. The expansion screws are embedded in the cabinet, and the positioning plate is inserted into the outer zone slot. The above solution also tries to balance large-area lighting and eye scattering protection. However, large-area lighting requires increasing the power of the LED chips, making it impossible to balance energy saving and large-area lighting.

[0006] Therefore, providing a drawer lamp that can increase the illumination range without power enhancement, does not illuminate the user's eyes during illumination, and is lightweight and thin to expand the illumination angle is a technical problem that urgently needs to be solved in this field.

[0014] The lower side plate, the first side plate, and part of the straight side plate form a second trapezoidal groove-shaped lamp strip cavity. The lamp strip is bonded to the straight side plate and the lower side plate inside the lamp strip cavity. The minimum angle between the lamp strip along its width extension direction and the lower side plate along its width extension direction is no greater than 60°. The lamp strip extends along the length direction of the lamp housing. The light from the lamp strip passes through the first side plate and shines directly away from the inner angle. The second side plate corresponding to the V-shaped structure has a corrugated surface on the side near the groove of the V-shaped structure. The corrugated surface extends along the length and width directions of the second side plate.

[0015] The control assembly includes a control board and a switch protective cover connected to the control board. The control board is electrically connected to the lamp strip and extends along the length of the lamp housing. The upper side plate, the inclined side plate, the second side plate, and part of the straight side plate form a control cavity in the shape of a third trapezoidal groove. The control board along the length of the lamp housing is snapped into the control cavity.

[0020] Compared with the prior art, the drawer lamp for expanding the illumination angle provided by this utility model achieves at least the following beneficial effects:

[0021] First, the drawer lamp provided by this utility model for expanding the illumination angle achieves wide-range, dead-angle-free lighting while saving energy and costs. Firstly, this utility model provides a herringbone-shaped lampshade, with a V-shaped structure formed between a portion of the second side panel and the first side panel. The opening of the V-shaped structure faces away from the side of the straight side panel, allowing the light strip illumination inside the lamp housing to undergo one refraction and one reflection through the lampshade. This refraction and reflection increase the illumination range. When the drawer lamp for expanding the illumination angle is applied to a cabinet, it refracts light into the deep, dead corners of the cabinet. Furthermore, a portion of the second side panel has a corrugated surface, allowing the light refracted by the first side panel to be reflected again by the corrugated surface of the second side panel. The reflected light further enhances the illumination range of the light strip.

[0022] Secondly, the drawer lamp provided by this utility model for expanding the illumination angle can provide wide-range, blind-spot-free illumination without causing direct damage to the user's eyes. Firstly, when the drawer lamp for expanding the illumination angle is installed above the drawer opening, the light from the light strip does not directly shine into the user's eyes. Furthermore, the corrugated surface of the second side panel further scatters the light during the secondary refraction process, which can effectively reduce the light intensity near the cabinet door, thereby enhancing the softness of the light.

[0023] Third, the drawer lamp for expanding the illumination angle provided by this utility model is lightweight and easy to install. Firstly, by optimizing the structure of the herringbone-shaped lampshade, this utility model effectively reduces the actual length of the lamp strip and the need for high-power LED beads required for corresponding lighting requirements. This effectively reduces the overall weight of the drawer lamp for expanding the illumination angle, making it lighter and thinner. Furthermore, part of the second side panel in the lampshade has a corrugated surface structure, which can diffuse and reflect light secondaryly, thereby increasing the illumination range, and further reducing the size by simplifying the mechanism.

[0024] Of course, any product implementing this utility model does not necessarily need to achieve all the technical effects described above at the same time.

[0068] Specifically, continue to refer to Figures 2-6As shown, the lamp housing 1 includes a first trapezoidal groove-shaped lamp outer shell 11 and a herringbone-shaped lamp shade 12. The lamp shade 12 is snapped and fixed to one side of the lamp outer shell 11 along the length X of the lamp housing 1. The lamp outer shell 11 and the lamp shade 12 can be made of plastic, specifically polycarbonate or polymethyl methacrylate, etc. The lamp outer shell 11 includes an upper side plate 111 and a lower side plate 112 arranged relatively parallel to each other. Both the upper side plate 111 and the lower side plate 112 are rectangular plates of the same length. The area of ​​the upper side plate 111 is smaller than the area of ​​the lower side plate 112. Specifically, the area of ​​the upper side plate 111 is less than half the area of ​​the lower side plate 112. A straight side plate 113 is integrally and equally long along the length X of the lamp housing 1 between the upper side plate 111 and the lower side plate 112. The straight side plate 113 is perpendicularly connected to one side of the upper side plate 111 and the lower side plate 112 on opposite sides of its width, and the extension direction of this perpendicular connection is along the length X of the lamp housing 1. The width Y of the straight side plate 113 is perpendicular to the length X of the lamp housing 1. The straight side plate 113, the upper side plate 111 and the lower side plate 112 form a groove-shaped cavity that extends along the length X of the lamp housing 1, has a right trapezoidal cross section and is open at both ends. The width Z of the lower side plate 112, the width Y of the straight side plate 113 and the length X of the lamp housing 1 are all perpendicular to each other.

[0069] There is a rectangular gap between the side of the inclined side plate 114 away from the upper side plate 111 and the lower side plate 112. The width of the gap along the width direction Y of the straight side plate 113 is greater than the width of the inclined side plate 114 along the width direction Y of the straight side plate 113. The gap is the opening of the first trapezoidal groove, which is used to engage the lampshade 12 and allow light to pass through the lampshade 12 and the light strip 2 inside the lamp housing 11.

[0070] A herringbone-shaped lampshade 12 is inserted into a slot in the lamp housing 11 from one end of the lamp housing 1 along the length X of the lamp housing 1. The lampshade 12 includes a first side plate 122 and a second side plate 123. The first side plate 122 and the second side plate 123 are rectangular plates of equal length. The first side plate 122 and the second side plate 123 are integrally formed by extrusion molding along the length X of the lamp housing 1 using a mold. The length of the first side plate 122 and the second side plate 123 along the length X of the lamp housing 1 is less than the length of the lamp housing 1. The first side plate 122 is made of translucent polymethyl methacrylate or polycarbonate, and the second side plate 123 is made of opaque material. A portion of the second side plate 123 forms a V-shaped structure with the first side plate 122. The cross-sectional shape of the first side plate 122 and a portion of the second side plate 123 along the width Y direction of the straight side plate 113 is V-shaped. The two ends of the straight side plate 113 are open along the length X of the lamp housing 1 along the width Y direction. The perpendicular line of the V-shaped structure intersects the perpendicular line of the straight side plate 113. The slot of the V-shaped structure is away from the straight side plate 113 and is on the same imaginary plane as the inclined side plate 114.

[0071] Continue to refer to Figures 2-4 As shown, the side of the second side plate 123 away from the inclined side plate 114 contacts the side of the straight side plate 113 near the inclined side plate 114, and the other end of the second side plate 123 is engaged with the inclined side plate 114. The lower side plate 112, the first side plate 122, and part of the straight side plate 113 form a lamp strip cavity 13. The lamp strip cavity 13 is a second trapezoidal groove extending along the length direction X of the lamp housing 1, and the cross-sectional shape of the lamp strip cavity 13 along the width direction Y of the straight side plate 113 is trapezoidal; the lower base of the second trapezoidal groove is larger than its upper base; the lower base of the second trapezoidal groove is the first side plate 122, and the trapezoidal inclined side of the second trapezoidal groove away from the lower side plate 112 and the side of the second side plate 123 near the slot of the V-shaped structure are in the same imaginary plane. A light strip 2, extending along the length of the lamp housing 1, is bonded inside the light strip cavity 13. The light strip 2 can be COB-08. The illumination direction of the light strip 2 is from the top surface of the second trapezoidal groove to its bottom surface. The side of the first side panel 122 near the groove of the V-shaped structure is corrugated. When the drawer light fixture used to expand the illumination angle is applied to the cabinet 01, the light from the light strip 2 penetrates the bottom surface of the second trapezoidal groove, i.e., the first side panel 122, and directly illuminates the area away from the inner angle. The first side panel 122 also scatters the light. Some of the scattered light is refracted a second time through the corrugated surface of the second side panel 123 into the area deep within the cabinet 01. Through the first side panel 122 with its V-shaped structure and the corrugated surface of the second side panel 123, full-area illumination can be achieved for the area of ​​the drawer near or away from the cabinet door, increasing the illumination area.

[0072] Specifically, the lower side plate 112 has a first C-shaped groove recessed in the direction away from the upper side plate 111 on the side closest to the upper side plate 111 and away from the straight side plate 113. The first C-shaped groove is rectangular, and its opening direction is parallel to the width direction Y of the straight side plate 113. The outer wall of the first side plate 122 near the slot of the V-shaped structure is integrally provided with a first I-shaped strip that matches and engages with the first C-shaped groove. The first I-shaped strip is rectangular, and its width along the width direction Z of the lower side plate 112 is smaller than the width of the first C-shaped groove in the lower side plate 112. The length direction of both the first C-shaped groove and the first I-shaped strip is along the length direction X of the lamp housing 1. The first C-shaped groove and the first I-shaped strip are used to allow the slot of the V-shaped structure of the lamp cover 12 and the corresponding connecting angle of the first side plate 122 to slide into the lower side plate 112.

[0073] An L-shaped groove is integrally formed on the side of the straight side plate 113 near the inclined side plate 114, with the inner right angle of the L-shaped groove facing the groove opening of the V-shaped structure. The cross-sectional shape of the L-shaped groove along the width direction Z of the lower side plate 112 is L-shaped, and the length of the short side of the L-shaped groove is not less than the thickness of the second side plate 123.

[0074] A second I-shaped strip is integrally formed on the side of the inclined side plate 114 away from the upper side plate 111. The second I-shaped strip is rectangular. A second C-shaped groove is formed on the side of the second side plate 123 near the straight side plate 113, which matches and engages with the second I-shaped strip. The second C-shaped groove is recessed towards the lower side plate 112. The width of the second I-shaped strip along the width direction Y of the straight side plate 113 is equal to the depth of the second C-shaped groove along the width direction Y of the straight side plate 113. The length direction of both the second I-shaped strip and the C-shaped groove is along the length direction X of the lamp housing 1. The second I-shaped strip and the C-shaped groove are used to allow the connection angles of the second side plate 123 of the lamp cover 12 and the corresponding slots of the V-shaped structure to slide and engage with the upper side plate 111.

[0075] Through the mutual matching and snapping between the first I-shaped groove and the first I-shaped strip, between the L-shaped groove and part of the second side plate 123, and between the second I-shaped groove and the second I-shaped strip, the lamp housing 11 and the lampshade 12 can be slidably connected, allowing the lamp housing 11 and the lampshade 12 to be directly assembled. Furthermore, the mutual matching and snapping between the first I-shaped groove and the first I-shaped strip, the L-shaped groove and part of the second side plate 123, and between the second I-shaped groove and the second I-shaped strip can form a triangular structure between the lamp housing 11 and the lampshade 12, making the connection between the lamp housing 11 and the lampshade 12 more stable.

[0076] Continue to refer to Figure 2 and Figure 4As shown, the upper side plate 111, the inclined side plate 114, the second side plate 123, and part of the straight side plate 113 form a control cavity 14. The control cavity 14 is a third trapezoidal groove extending along the length X of the lamp housing 1. The cross-sectional shape of the control cavity 14 along the width Y of the straight side plate 113 is trapezoidal. The lower base of the third trapezoidal groove is larger than its upper base. The lower trapezoidal base of the third trapezoidal groove is part of the straight side plate 113, and the upper base of the third trapezoidal groove is the inclined side plate 114. The inclined side of the trapezoidal groove corresponds to the second side plate 123 as the groove wall. A control plate 31 along the length X of the lamp housing 1 is snapped into the control cavity 14.

[0077] Continue to refer to Figure 2 , Figure 4 , Figure 7 and Figure 8 As shown, the control assembly 3 includes a control board 31 and a switch protective cover 32. The switch protective cover 32 is in contact with the control board 31. The control board 31 is used to control the switching on and off of the light strip 2. The length of the control board 31 is X along the length direction of the lamp housing 1; the control board 31 is further engaged in the control cavity 14 along its length direction. The perpendicular bisector of the control board 31 is parallel to the perpendicular bisector of the upper side plate 111.

[0078] The switch protective cover 32 is used to protect the inductive switch on the control board 31. Specifically, an inductive through hole 1111 is provided at the geometric center of the upper side plate 111, extending through the upper side plate 111 along the width direction Y of the straight side plate 113. The inductive through hole 1111 is rectangular in shape; the perpendicular bisector of the inductive through hole 1111 is parallel to the perpendicular bisector of the upper side plate 111; the width of the inductive through hole 1111 along the width direction Z of the lower side plate 112 is not greater than the width of the upper side plate 111 along the width direction Z of the lower side plate 112. The inductive through hole 1111 is used to pass through the outside of the control cavity 14 and the lamp housing 11. The switch protective cover 32 is snapped and fixed inside the rectangular inductive through hole 1111; the side of the switch protective cover 32 closest to the control cavity 14 is inserted into the control board 31 inside the control cavity 14, and the switch protective cover 32 is placed inside the inductive through hole 1111. The switch protective cover 32 passes through the induction through hole 1111 and is inserted into the control board 31 to fix the control board 31 along the length X of the lamp housing 1.

[0079] Continue to refer to Figures 2-4 ,as well as Figures 9-12 As shown, the fixing component 4 includes a trapezoidal left fixing member 41 and a right fixing member 42. The left fixing member 41 includes a left clip 411 fixed to the inner wall of one side of the cabinet 01 with screws, and a left plug 412 for connecting the left clip 411 and the lamp housing 1 near the end of the left clip 411; the right fixing member 42 includes a right clip 421 fixed to the inner wall of one side of the cabinet 01 with screws, and a right plug 422 for connecting the right clip 421 and the other end of the lamp housing 1.

[0080] The left and right latches 411 and 421 are the same size, and their structures are mirror-symmetrical about the mid-plane of the straight side plate 113 along the length X of the lamp housing 1. Both the left and right latches 411 and 421 are L-shaped pieces. The left latch 411 is fixed to the left side of the cabinet 01 along its door opening direction by screws, and the other side of the left latch 411 away from the cabinet 01 is engaged with the left end cap 412. The right latch 421 is fixed to one side of the cabinet 01 along its door opening direction by screws, and the other side of the right latch 421 away from the cabinet 01 is engaged with the right end cap 422.

[0081] The left end cap 412 and the right end cap 422 are the same size. The structures of the left end cap 412 and the right end cap 422 are mirror-symmetrical about the vertical plane of the straight side plate 113 along the length direction X of the lamp housing 1. Both the left end cap 412 and the right end cap 422 have a V-shaped rectangular strip 402 on the side near the lamp cover 12; the V-shaped opening of the rectangular strip 402 faces the groove of the V-shaped structure. Along the length direction X of the lamp housing 1, the orthographic projection of the rectangular strip 402 coincides with the orthographic projection of the lamp housing 11, and the orthographic projection of the rectangular strip 402 in the left end 412 is tangent to one side of the orthographic projection of the lampshade 12, and the orthographic projection of the rectangular strip 402 in the left end 412 is tangent to the side of the orthographic projection of the lampshade 12 away from the rectangular strip 402 in the left end 412; that is, along the length direction X of the lamp housing 1, the sum of the thickness of the rectangular strip 402 in the left end 412, the thickness of the rectangular strip 402 in the right end 422, and the length of the lampshade 12 is equal to the length of the lamp housing 11. The rectangular strip 402 of the left end cap 412 and the rectangular strip 402 of the right end cap 422 respectively contact the two ends of the lamp cover 12 along the length X of the lamp housing 1; the side of the left end cap 412 away from the left clip 411 is snapped into the groove cavity on one side of the first trapezoidal groove body by the rectangular strip 402 in the left end cap 412 and fixed with a self-tapping screw, and the side of the right end cap 422 away from the right clip 421 is snapped into the groove cavity on the other side of the first trapezoidal groove body by the rectangular strip 402 in the right end cap 422 and connected with a self-tapping screw.

[0082] Optionally, the width of the lower side plate 112 perpendicular to the length of the lamp housing 1 is 10 mm.

[0083] Specifically, if the width of the lower side panel 112 perpendicular to the length of the lamp housing 1 is less than 10mm, it will result in insufficient installation space for lamp accessories (such as light strips and control board 31); if the width of the lower side panel 112 perpendicular to the length of the lamp housing 1 is greater than 10mm, it will occupy cabinet 01 (such as... Figure 22To address the issue of insufficient space for lamp accessories (such as light strips and control board 31) and the resulting unrefined appearance, this embodiment designs the lower side panel 112 with a width of 10mm perpendicular to the length of the lamp housing 1. This not only avoids insufficient installation space for lamp components (such as light strips and control board 31) but also prevents the cabinet 01 from being occupied, while simultaneously improving the appearance of the cabinet 01. Optionally, the upper side panel 111 with a width perpendicular to the length of the lamp housing 1 is smaller than the lower side panel 112 with a width perpendicular to the length of the lamp housing 1.

[0084] In the specific implementation process, continue to refer to Figures 5-8 , Figure 10 ,as well as Figures 12-14 As shown, Figure 13 This is a structural schematic diagram of a drawer lamp for expanding the illumination angle provided by this utility model; Figure 14 This is a flowchart illustrating the assembly process of a drawer lamp for expanding the illumination angle, provided by this utility model; the specific installation operations are as follows:

[0085] Step S1, combined Figure 7 and Figure 14 As shown, the control board 31 of the drawer lamp used to expand the illumination angle is installed as follows: the electronic component side of the control board 31 faces the upper side plate 111 of the lamp housing 11, so that the control board 31 slides into the lamp housing 11 from one end along the length direction X of the lamp housing 1, specifically into the control cavity 14 of the lamp housing 11; then the vertical line of the control board 31 is parallel to the vertical line of the upper side plate 111, and the orthographic projection of the sensing through hole 1111 on the upper side plate 111 coincides with the orthographic projection of the control board 31 along the width direction Y of the straight side plate 113. The control board 31 has a slot, and can be directly exposed through the sensing through hole 1111 on the upper side plate 111.

[0086] Step S2, combined with 2, Figure 8 and Figure 14 As shown, the installation of the switch protection cover 32 is as follows: along the width direction Y of the straight side plate 113, the switch protection cover 32 is inserted from the side of the upper side plate 111 away from the lower side plate 112 towards the lower side plate 112, so that the switch protection cover 32 passes through the sensing through hole 1111 and is snapped onto the control plate 31, thus completing the fixed connection of the control plate 31, the switch protection cover 32, and the outer shell 11.

[0087] Step S3, combined Figure 4 , Figure 5 and Figure 14 As shown, the installation of the light strip 2 is as follows: The light strip 2 is pasted along the length X of the lamp housing 1 to the light strip cavity 13 of the lamp housing 11, specifically pasted to the bottom surface of the second trapezoidal groove of the light strip cavity 13.

[0088] Optionally, the fourth step can only be performed after the third step is completed. The first, second and third steps can be implemented in different ways. In this embodiment, the control board 31 is installed first, then the protective cover 32 is switched on and off, and finally the light strip 2 is installed. This is not a limitation on the order of these three installation steps.

[0089] Step S4, combined Figure 6 and Figure 14 As shown, the lampshade 12 is installed by sliding one end of the lamp housing 11 into the U-shaped structure of the lamp housing 11, specifically between the light strip 2 and the control board 31, so that the vertical plane of the lampshade 12 perpendicular to its length direction is on the same imaginary plane as the vertical plane of the lamp housing 11 perpendicular to its length direction, and the first apex of the lampshade 12 contacts the straight side plate 113 of the lamp housing 11; the first apex is the apex of the V-shaped structure.

[0090] Step S5, combined Figure 11 , Figure 12 and Figure 14 As shown, the left end cap 412 and the right end cap 422 are installed such that their rectangular strips 402 face each other. The side of the left end cap 412 closest to its rectangular strip 402 contacts one end of the lamp housing 11 along the length X direction of the lamp housing 1 and is connected by a screw. The side of the right end cap 422 closest to its rectangular strip 402 contacts the other end of the lamp housing 11 along the length X direction of the lamp housing 1 and is connected by a screw.

[0091] Compared with the prior art, the drawer lamp for expanding the illumination angle provided in this embodiment achieves at least the following beneficial effects:

[0092] First, the drawer lamp provided in this embodiment for expanding the illumination angle achieves wide-range, dead-angle-free illumination while saving energy and costs. Firstly, this embodiment provides a herringbone-shaped lampshade 12, with a V-shaped structure formed between a portion of the second side panel 123 and the first side panel 122. The opening of the V-shaped structure faces away from the side of the straight side panel 113, allowing the illumination of the light strip 2 within the lamp housing 11 to undergo one refraction and one reflection through the lampshade 12. This refraction and reflection increase the illumination range. When the drawer lamp for expanding the illumination angle is applied to the cabinet 01, it refracts the light into the deep, dead-angle areas of the cabinet 01. Furthermore, a portion of the second side panel 123 has a corrugated surface, allowing the light refracted by the first side panel 122 to be reflected again by the corrugated surface of the second side panel 123. The reflected light further enhances the illumination range of the light strip 2.

[0093] Secondly, the drawer light fixture provided in this embodiment, which expands the illumination angle, provides wide-range, blind-spot-free illumination without causing direct damage to the user's eyes. Firstly, when the drawer light fixture for expanding the illumination angle is installed above the drawer opening, the light emitted by the light strip 2 does not directly shine into the user's eyes. Furthermore, the corrugated surface of the second side panel 123 further scatters the light during the secondary refraction process, which can effectively reduce the light intensity near the cabinet door, thereby enhancing the softness of the light.

[0094] Third, the drawer lamp provided in this embodiment for expanding the illumination angle is lightweight and easy to install. Firstly, by optimizing the structure of the herringbone-shaped lampshade 12, this embodiment effectively reduces the actual length of the light strip 2 and the need for high-power LEDs required for the corresponding lighting requirements. This effectively reduces the overall weight of the drawer lamp for expanding the illumination angle, making it lighter and thinner. Furthermore, part of the second side plate 123 in the lampshade 12 has a corrugated surface structure, which can diffuse and reflect light secondaryly, thereby increasing the illumination range, and further reducing the size by simplifying the mechanism.

[0095] In one alternative embodiment, continue to refer to Figure 2 and Figure 15 As shown, Figure 15 This is a circuit logic diagram of a drawer lamp for expanding the illumination angle provided by this utility model; in this embodiment, the control component 3 also includes a transformer 35 placed in the control cavity 14, the control board 31 includes a sensor switch 313 and a circuit board 312, the circuit board 312 is a rectangular plate, the circuit board 312 is snapped and fixed in the control cavity 14 along the length X of the lamp housing 1, the sensor switch 313 is integrated into the circuit board 312, one end of the circuit board 312 along the length X of the lamp housing 1 is electrically connected to the transformer 35 through an external wire 406, and the other end is electrically connected to the lamp strip 2 through an internal wire 405, the sensor switch 313 is placed in the switch protection cover 32.

[0096] Specifically, the control board 31 includes a motion sensor switch 313 and a circuit board 312. The motion sensor switch 313, the light strip 2, the transformer 35 and the circuit board 312 are electrically connected; the motion sensor switch 313, the transformer 35 and the circuit board 312 are all placed inside the control cavity 14.

[0097] The aforementioned inductive switch 313 is an infrared sensor, specifically model HW-50, which is integrated and soldered onto circuit board 312 and housed together with circuit board 312 in control cavity 14. Inductive switch 313 is used to sense changes in the drawer opening and closing mechanism.

[0098] The circuit board 312 is a rectangular plate that mechanically supports the induction switch 313 and receives sensing information from the induction switch 313 to instruct the light strip 2 to open and close. Specifically, the circuit board 312 integrates the induction switch 313, which senses the drawer switch and issues power-on / off commands. Simultaneously, lamp wires are soldered to both ends of the circuit board; one end connects to a transformer for power, and the other end supplies power to the light strip 2. The circuit board 312 is composed of insulating and conductive materials. By laying conductive lines on the insulating material, it senses the opening and closing of the drawer and controls the power supply. The model number of the circuit board 312 can be D24V08CA02. The length of the circuit board 312 extends along the length direction X of the lamp housing 1, and the width extends along the width direction Z of the lower side plate 112. Along the length direction X of the lamp housing 1, the circuit board 312 is snap-fitted and fixed within the control cavity 14.

[0099] Transformer 35 is an electronic component that converts electrical energy from the voltage level of power socket 33 to the voltage level of light strip 2. It is an electrical device that works based on the principle of electromagnetic induction, achieving voltage conversion by transferring magnetic flux between two or more windings. The model of transformer 35 can be K24V65CA03. The other end of transformer 35 away from circuit board 312 is connected to external power socket 33.

[0100] The above scheme enables the control board 31 to receive and read light signals, and further control the light strip 2 to open and close. At the same time, the transformer 35 can convert the power supply voltage and supply power to the light strip 2 through the circuit board 312, so that when the cabinet 01 is opened, the light strip 2 inside the drawer cabinet will automatically turn on, and when the drawer is pulled back to close, the light strip 2 inside the drawer cabinet will automatically turn off.

[0101] In one alternative embodiment, continue to refer to Figure 2 and Figure 3 As shown, the inclined side plate 114 has a lower circuit board slot recessed in the direction away from the straight side plate 113 on the side near the straight side plate 113, and the lower circuit board slot is located at one end of the inclined side plate 114 near the second side plate 123; the straight side plate 113 has an upper circuit board slot recessed in the direction away from the inclined side plate 114 on the side near the inclined side plate 114; along the width direction Z of the lower side plate 112, the orthographic projection of the upper circuit board slot and the orthographic projection of the lower circuit board slot coincide with each other; both the lower circuit board slot and the upper circuit board slot are C-shaped slots.

[0102] The circuit board 312 is respectively snapped into the upper power board slot and the lower power board slot on both sides along its width direction; the width of the upper power board slot and the lower power board slot along the width direction Y of the straight side plate 113 is not less than the thickness of the circuit board 312.

[0103] Specifically, the inclined side plate 114 has a lower circuit board slot recessed in a direction away from the straight side plate 113 on the side near the straight side plate 113. The lower circuit board slot is specifically located at one end of the inclined side plate 114 near the second side plate 123. The lower circuit board slot is a C-shaped slot with its opening facing the upper circuit board slot, and the cross-sectional shape of the lower circuit board slot along the width direction Y of the straight side plate 113 is C-shaped.

[0104] A recessed upper circuit board slot is provided on the side of the straight side plate 113 near the inclined side plate 114, extending away from the inclined side plate 114. The upper circuit board slot is a C-shaped slot with its opening facing the lower circuit board slot, and its cross-sectional shape along the width Y direction of the straight side plate 113 is C-shaped. Along the width Z direction of the lower side plate 112, the orthographic projections of the upper and lower circuit board slots coincide; the lengths of the upper and lower circuit board slots along the length X direction of the lamp housing 1 are equal to the lengths of the lamp housing 11 along the length X direction of the lamp housing 1. A circuit board 312 is slidably engaged between the upper and lower circuit board slots.

[0105] Specifically, circuit board 312 is inserted into the lamp housing 11 from one end along the length X of the lamp housing 1, and the two sides of circuit board 312 along its width direction are respectively engaged in the upper power board slot and the lower power board slot. The width of the upper power board slot and the lower power board slot along the width Y of the straight side plate 113 is not less than the thickness of circuit board 312. The distance between the bottom of the upper power board slot and the bottom of the lower power board slot is greater than the width of circuit board 312 along the width Z of the lower side plate 112; the distance between the opening of the upper power board slot and the opening of the lower power board slot is less than the width of circuit board 312 along the width Z of the lower side plate 112.

[0106] The above solution enables quick plug-in installation of the circuit board 312 and the lamp housing 11. This plug-in installation can save on the increased installation cost caused by the use of connectors. On the other hand, the reduction of connectors can optimize and lighten the overall structure, making the connection more compact and concentrated, and further making the device thinner and smaller.

[0107] In one alternative embodiment, continue to refer to Figure 11 ,as well as Figures 16-19 As shown, Figure 16 This is a partial structural diagram of a drawer lamp for expanding the illumination angle provided by this utility model at one angle; Figure 17 This is a partial structural diagram of the drawer lamp for expanding the illumination angle provided by this utility model from another angle; Figure 18 This is a partial structural diagram of the drawer lamp for expanding the illumination angle provided by this utility model from another angle; Figure 19This is a partial structural diagram of the drawer lamp for expanding the illumination angle provided by this utility model from another angle; the left end 412 and the right end 422 are both provided with a rectangular first wire through hole 401 that runs through the left end 412 or the right end 422 along the length direction X of the lamp housing 1; the orthographic projection of the first wire through hole 401 along the length direction X of the lamp housing 1 is located in the orthographic projection of the control cavity 14; the left end 412 and the right end 422 away from the first wire through hole 401 are both provided with a trapezoidal second wire through hole 404 that runs through the left end 412 or the right end 422 along the width direction Y of the straight side plate 113.

[0108] The V-shaped apex of the rectangular strip 402 is a through-angle parallel to the inclined side plate. The rectangular strip 402 abuts against the lampshade 12. The through-angle is parallel to the inclined side plate 114. The lamp strip cavity 13 and the control cavity 14 form gaps with the through-angle respectively. The internal wire 405 passes through the gap from the lamp strip cavity 13 into the control cavity 14 and is electrically connected to the circuit board 312. The external wire 406 passes through the second wire through hole 404 and the first wire through hole 401 in sequence and is electrically connected to the circuit board 312 in the control cavity 14.

[0109] Specifically, both the left end cap 412 and the right end cap 422 have a first wire through hole 401 extending along the length X of the lamp housing 1 through the left end cap 412 or the right end cap 422 near the upper side plate 111; the first wire through hole 401 is rectangular in shape. Along the length X of the lamp housing 1, the orthographic projection of the first wire through hole 401 does not coincide with the orthographic projection of the rectangular strip 402, and the orthographic projection of the first wire through hole 401 is located within the orthographic projection of the control cavity 14. The first wire through hole 401 is used to connect the control cavity 14 to the outside of the left end cap 412 or the right end cap 422. At the end of the left end cap 412 and the right end cap 422 away from the first wire through hole 401 and near the lower side plate 112, a second wire through hole 404 extending along the width Y of the straight side plate 113 through the left end cap 412 or the right end cap 422 is provided. The second wire through hole 404 is trapezoidal in shape. The second wire through hole 404 and the first wire through hole 401 are connected and pass through each other inside the left plug 412 or the right plug 422. The second wire through hole 404 is used to comb and fix the wires extending from the first wire through hole 401.

[0110] The V-shaped apex of the rectangular strip 402 is a through-angle, parallel to the sloping side plate 114. After the rectangular strip 402 abuts against the lampshade 12, the through-angle remains parallel to the sloping side plate 114, forming gaps between the lamp strip cavity 13 and the control cavity 14, thus allowing connection between them. Furthermore, the rectangular strip 402 covers the internal wire 405, preventing it from passing through the lampshade 12 on the side closest to the lamp housing 11, thus preventing the internal wire 405 from being exposed on the lampshade 12 and casting a shadow. In the specific wiring process, the end of the light strip 2 closest to the left end cap 412 or the right end cap 422 is connected to the internal wire 405. The internal wire 405 passes through the flat angle of the rectangular strip 402 from the light strip cavity 13 into the control cavity 14 and is electrically connected to the circuit board 312. The internal wire 405 is a power transmission line, which completes the power input through the circuit board 312 and controls the switching of the light strip 2. The external wire 406 passes through the second wire through hole 404 and the first wire through hole 401 in sequence, and is electrically connected to the transformer 35 in the control cavity 14. The other end of the external wire 406 away from the transformer 35 is connected to the 220V power socket 33 outside the lamp housing for power supply. The external wire 406 is also a power transmission line.

[0111] Through the above scheme, the internal wire 405 and the external wire 406 can be arranged in a specific way. During the arrangement process, the internal wire 405 can be fixed by the gap formed by the through-angle, and the external wire 406 can be further fixed by the first wire through hole 401 and the second wire through hole 404. This makes the wiring of the drawer lamp for expanding the illumination angle provided in this embodiment simpler, reduces the waste of excessively long internal wires 405 and external wires 40 due to messy wiring, saves the length of internal wires 405 and external wires 406, and also reduces the actual weight of the drawer lamp for expanding the illumination angle. At the same time, it does not occupy too much space in the lamp cavity, so that the overall size of this embodiment can be thinner and smaller.

[0112] In one alternative embodiment, continue to refer to Figure 2 , Figure 4 , Figure 11 , Figure 12 and 22 As shown, C-shaped grooves are glued to both ends of the straight side plate 113 near the inclined side plate 114 along its length direction.

[0114] Specifically, on the side of the straight side plate 113 near the inclined side plate 114, C-shaped grooves are glued to both ends along its length. The length direction of the C-shaped groove is the length direction X of the lamp housing 1. The opening of the C-shaped groove can face any direction excluding the width direction Z of the lower side plate 112. The cross-sectional diameter of the C-shaped groove is not less than 1.5mm. The opening of the C-shaped groove is used to generate elasticity, so that when the self-tapping screw is tightened into the C-shaped groove along the length direction X of the lamp housing 1, a holding force can be generated. Along the length direction X of the lamp housing 1, the orthographic projection of the C-shaped groove coincides with the orthographic projection of the control cavity 14.

The thickness of the rectangular protrusion 4021 along the width direction Z of the lower side plate 112 is equal to the thickness of the first I-shaped strip along the width direction Z of the lower side plate 112. Along the length direction X of the lamp housing 1, the orthographic projection of the rectangular protrusion 4021 coincides with the orthographic projection of the first I-shaped strip. A chamfered groove 4022, which matches and engages with the second I-shaped strip, is integrally provided at one end of the rectangular strip 402 near the inclined side plate 114. The width of the chamfered groove 4022 along the width direction Z of the lower side plate 112 is equal to the width of the second chamfered groove along the width direction Z of the lower side plate 112. Along the length direction X of the lamp housing 1, the orthographic projection of the second chamfered groove coincides with the orthographic projection of the chamfered groove 4022.

[0118] Through the above scheme, the circular through hole 403 and the C-shaped groove can connect and fix the left plug 412 and the lamp housing 11, as well as the right plug 422 and the other end of the lamp housing 11; the chamfered groove 4022 and the rectangular protrusion 4021 can connect the rectangular strip 402 on the left plug 412 and the lampshade 12, thus limiting the left plug 412 before screwing in the self-tapping screw, and the rectangular strip 402 on the right plug 422 and the other end of the lampshade 12 can connect the right plug 422 before screwing in the self-tapping screw. Furthermore, the rectangular strip 402 on the left plug 412 is fixedly connected to the left plug 412, and the rectangular strip 402 on the right plug 422 is fixedly connected to the right plug 422, which can further increase the limiting relationship formed between the left plug 412 and the right plug 422 and the lamp housing 1, facilitating the screwing in of the self-tapping screw.

[0119] In one alternative embodiment, continue to refer to Figure 2 , Figure 10 and Figure 20 As shown, Figure 20 yes Figure 2 Enlarged view at point B; both the left clip 411 and the right clip 421 include a trapezoidal piece 4081 and a pin 4082 connected to the trapezoidal piece 4081, and part of the trapezoidal piece 4081 and the pin 4082 form a first L-shaped structure;

[0120] The width of the pin 4082 along the length X of the lamp housing 1 is not greater than the thickness of the left end cap 412 or the right end cap 422 along the length X of the lamp housing 1; along the length X of the lamp housing 1, the orthographic projection of the pin 4082 coincides with the orthographic projection of the left end cap 412 or the right end cap 422; a fixing through hole 4111 is provided on the trapezoidal piece 4081, the fixing through hole 4111 passes through the trapezoidal piece 4081 along the length X of the lamp housing 1, and the orthographic projection of the pin 4082 does not overlap with the orthographic projection of the fixing through hole 4111.

[0121] The left end cap 412 has a left rectangular groove 4121 on the side away from its rectangular strip 402, which passes through the left clip 411 along the width direction Y of the straight side plate 113. The opening of the left rectangular groove 4121 faces the left clip 411 and is slidably inserted into the pin 4082 of the left clip 411.

[0122] The right end cap 422 has a right rectangular groove 4221 on the side away from its rectangular strip 402, which extends through the right clip 421 along the width direction Y of the straight side plate 113. The opening of the right rectangular groove 4221 faces the right clip 421 and is slidably inserted into the pin 4082 of the right clip 421.

[0123] Specifically, both the left latch 411 and the right latch 421 include a trapezoidal piece 4081 and a pin 4082 perpendicularly connected to one wide surface of the trapezoidal piece 4081. The trapezoidal piece 4081 is a right-angled trapezoid, and part of the trapezoidal piece 4081 and the pin 4082 form a first L-shaped structure. Along the length direction X of the lamp housing 1, the orthographic projection of the trapezoidal piece 4081 coincides with the orthographic projection of the left end cap 412 or the right end cap 422. Along the direction from the upper bottom surface of the trapezoidal piece 4081 to its lower bottom surface, the pin 4082 forms the right latch 421 when it is on the left wide surface of the trapezoidal piece 4081, and forms the left latch 411 when it is on the right wide surface of the trapezoidal piece 4081. The right latch 421 and the left latch 411 are the same size, and the left latch 411 and the right latch 421 are mirror-symmetrical.

[0124] Pin 4082 is used to achieve the engagement of left latch 411 and left plug 412, and right latch 421 and right plug 422. The width of pin 4082 along the length X of lamp housing 1 is not greater than the thickness of left plug 412 or right plug 422 along the length X of lamp housing 1, thereby enabling seamless engagement between left latch 411 and left plug 412, and between right latch 421 and right plug 422. Along the length X of lamp housing 1, the orthographic projection of pin 4082 coincides with the orthographic projection of left plug 412 or right plug 422. A fixing through hole 4111 is provided on the trapezoidal piece 4081, which extends through the length X of the lamp housing 1. The through direction of the fixing through hole 4111 is the same as the thickness extension direction of the trapezoidal piece 4081. The trapezoidal piece 4081 is fixed to the cabinet 01 by screws through the fixing through hole 4111. The orthographic projection of the pin piece 4082 and the orthographic projection of the fixing through hole 4111 do not overlap.

[0125] The left end cap 412 has a left rectangular groove 4121 that extends through the left retainer 411 along the width Y direction of the straight side plate 113. The opening of the left rectangular groove 4121 faces the left retainer 411, meaning the left rectangular groove 4121 is recessed away from the left retainer 411. The length of the left rectangular groove 4121 along the width Y direction of the straight side plate 113 is not less than the length of the pin 4082 along the width Y direction of the straight side plate 113, and the depth of the left rectangular groove 4121 along the length X direction of the lamp housing 1 is not less than the depth of the pin 4082 along the length X direction of the lamp housing 1. The left rectangular groove 4121 is slidably inserted into the pin 4082 of the left retainer 411.

[0126] The right end cap 422 has a right rectangular groove 4221 that extends through the right retainer 421 along the width Y direction of the straight side plate 113. The opening of the right rectangular groove 4221 faces the right retainer 421, meaning the right rectangular groove 4221 is recessed away from the right retainer 421. The length of the right rectangular groove 4221 along the width Y direction of the straight side plate 113 is not less than the length of the pin 4082 along the width Y direction of the straight side plate 113, and the depth of the right rectangular groove 4221 along the length X direction of the lamp housing 1 is not less than the depth of the pin 4082 along the length X direction of the lamp housing 1. The right rectangular groove 4221 is slidably inserted into the pin 4082 of the right retainer 421.

[0127] Through the above scheme, the pin 4082 of the left locking piece 411 slides into the left rectangular groove 4121 of the left plug 412, thereby making the left locking piece 411 and the left plug 412 movably connected. The pin 4082 of the right locking piece 421 slides into the right rectangular groove 4221 of the right plug 422, thereby making the left locking piece 411 and the left plug 412 movably connected. Furthermore, this sliding connection is portable and quick, which can effectively improve the loading and use speed of this embodiment.

[0128] In one alternative embodiment, continue to refer to Figure 20 and Figure 21 As shown, Figure 21 This is a schematic diagram of the structure of the left plug provided by this utility model; a rectangular limiting piece 4083 is provided at one end of the pin piece 4082 near the upper side plate 111, and the limiting piece 4083 and the pin piece 4082 form a T-shaped structure; the side of the limiting piece 4083 near the trapezoidal piece 4081 is connected to the side of the trapezoidal piece 4081 near the pin piece 4082, and the limiting piece 4083 and part of the trapezoidal piece 4081 form a second L-shaped structure; the side of the limiting piece 4083 near the upper side plate 111 and the side of the trapezoidal piece 4081 near the upper side plate 111 are located on the same plane;

[0129] The pin 4082 is provided with an arc-shaped protrusion 4084 on the side near the straight side plate 113. The protrusion 4084 protrudes away from the pin 4082. Along the length direction X of the lamp housing 1, the orthographic projection of the protrusion 4084 completely coincides with the orthographic projection of the trapezoidal piece 4081.

[0130] Both the left end cap 412 and the right end cap 422 have a limiting groove on the side near the pin 4082 that matches the limiting piece 4083. The limiting groove is a rectangular groove that is recessed towards the lamp housing 11. The limiting groove is parallel to the left end cap 412 and the right end cap 422 and is coplanar with both sides of the straight side plate 113 and the upper side plate 111. The side of the limiting groove near the straight side plate 113 has a recessed point 4085 that matches the protrusion 4084. The limiting piece 4083 is engaged with the limiting groove, and the protrusion 4084 is engaged with the recessed point 4085.

[0131] Specifically, a rectangular limiting piece 4083 is vertically connected to one end of the pin 4082 near the upper side plate 111, and the pin 4082 and the limiting piece 4083 are integrally formed. The limiting piece 4083 and the pin 4082 form a T-shaped structure parallel to the trapezoidal piece 4081. The side of the limiting piece 4083 near the trapezoidal piece 4081 is also vertically connected to the side of the trapezoidal piece 4081 near the pin 4082, and the limiting piece 4083 and part of the trapezoidal piece 4081 form a second L-shaped structure; the side of the limiting piece 4083 near the upper side plate 111 and the side of the trapezoidal piece 4081 near the upper side plate 111 are on the same plane, and the side of the limiting piece 4083 near the straight side plate 113 and the side of the trapezoidal piece 4081 near the straight side plate 113 are on the same plane.

[0132] Both the left end cap 412 and the right end cap 422 have a limiting groove on the side near the pin 4082 that matches the limiting piece 4083. The limiting groove is a rectangular groove with its opening recessed towards the lamp housing 11. The side of the limiting groove near the upper side plate 111 is on the same plane as the side of the trapezoidal piece 4081 near the upper side plate 111, and the side of the limiting groove near the straight side plate 113 is on the same plane as the side of the trapezoidal piece 4081 near the straight side plate 113; that is, the limiting groove is coplanar with both the left end cap 412 and the right end cap 422, parallel to both sides of the straight side plate 113 and the upper side plate 111.

[0133] Furthermore, after the limiting piece 4083 of the pin 4082 engages with the limiting slot along the direction from the lower side plate 112 to the upper side plate 111, the pin 4082 may still return along the original path and fall out of the limiting slot. Therefore, an arc-shaped protrusion 4084 is further provided on the side of the pin 4082 near the straight side plate 113, and a recess 4085 matching the protrusion 4084 is further provided on the side of the limiting slot near the straight side plate 113. The arc-shaped protrusion 4084 can be an arc-shaped body or a semi-arc-shaped body (such as a semi-cylindrical shape). In this embodiment, a semi-cylindrical shape is used as an example. The length direction of the semi-cylindrical protrusion 4084 is the length direction X of the lamp housing 1. The arc-shaped surface of the protrusion 4084 protrudes towards the side away from the pin 4082. Along the length direction X of the lamp housing 1, the orthographic projection of the protrusion 4084 completely coincides with the orthographic projection of the pin 4082. In this embodiment, the recessed point 4085 is a semi-cylindrical groove with the semi-cylindrical protrusion 4084. When the user pushes the lamp housing 1 and the left end cap 412 and right end cap 422 at both ends to the maximum extent along the depth of the cabinet 01 towards the cabinet door, the protrusion 4084 and the recessed point 4085 are engaged in a convex-concave fit. At this time, along the length direction X of the lamp housing 1, the orthographic projection of the protrusion 4084 completely coincides with the orthographic projection of the trapezoidal piece 4081.

[0134] Through the above scheme, when the user pushes the lamp housing 1 and the left end caps 412 and right end caps 422 at both ends along the depth of the cabinet 01 towards the cabinet door, the pin 4082 of the left locking piece 411 can slide into the left rectangular groove 4121 of the left end cap 412, and the pin 4082 of the right locking piece 421 can slide into the right rectangular groove 4221 of the right end cap 422. When it slides to the maximum extent, the limiting card on the left locking piece 411 engages with the limiting card groove of the left locking piece 411, and the limiting card on the right locking piece 421 engages with the limiting card groove of the right locking piece 421, so that the lamp housing 1 and the left end caps 412 and right end caps 422 at both ends cannot continue to be pushed along the depth of the cabinet 01 towards the cabinet door, thereby achieving the effect of To limit the installation of the drawer lamp for expanding the illumination angle in this embodiment; furthermore, after the pin 4082 of the left latch 411 is inserted into the left rectangular groove 4121 of the left plug 412, and after the pin 4082 of the right latch 421 is inserted into the right rectangular groove 4221 of the right plug 422, it is still easy to fall off from the opposite direction of insertion. The pin 4082 of both the left latch 411 and the right latch 421 is provided with a protrusion 4084, and the left plug 412 and the right plug 422 are provided with a recess 4085 that matches the protrusion 4084. The convex-concave fit of the protrusion 4084 and the recess 4085 can prevent the drawer lamp for expanding the illumination angle from sliding off in the opposite direction of insertion.

[0135] In an alternative embodiment, continue to refer to Figures 2-14 As shown, the upper side plate 111 and the inclined side plate 114 are connected by side corners. The left end cap 412 is connected to the side corner by a corresponding extended corner, the right end cap 422 is connected to the side corner by a corresponding extended corner, the left clip 411 is connected to the side corner by a corresponding extended corner, and the right clip 421 is connected to the side corner by a corresponding extended corner, all of which are provided with chamfered surfaces.

[0136] Specifically, in this embodiment, the drawer lamp used to expand the illumination angle is connected to the upper side plate 111 and the inclined side plate 114 by a side edge, which extends along the length direction X of the lamp housing 1; along the length direction X of the lamp housing 1, the left end cap 412 and the right end cap 422 are provided with chamfered planes at the corresponding side edges, and the two ends of the side edges are in contact with the chamfered planes of the left end cap 412 and the right end cap 422, respectively.

[0137] The corners that extend and connect to the side corners, the corners that extend and connect to the right end 422 and the side corners, the corners that extend and connect to the left clip 411 and the side corners, and the corners that extend and connect to the right clip 421 and the side corners are all flattened to form chamfered planes; that is, the corners of the drawer lamps used to expand the illumination angle in the embodiment that are close to the cabinet door are all flattened to form chamfered planes.

[0138] The above solution reduces the risk of collision damage to the drawer light fixture used to expand the illumination angle when the user opens the cabinet door. It also ensures that even if the cabinet door is bumped during opening and closing, the bumped edge is smooth, thus effectively reducing the risk of collision damage during use.
